Welcome to The Engineering Scientist's Notebook, an evolving database that bridges rigorous science and practical engineering. This platform is a curated archive of my personal notes, compiled over years of academic research and professional engineering practice and structured around three core pillars. Mathematics covers foundations such as complex numbers, random variables, vector calculus, and transforms, often applied in science and engineering. Physics presents fundamental phenomena in nature and their mathematical models, including mechanics, field theory, and relativity. Engineering synthesises these frameworks, combining mathematics and physics to cover applied topics like signal theory, circuits, systems, and communication networks.

Unlike traditional textbooks, which are either buried under dense scientific formalism or oversimplified into ready-to-use engineering recipes, this site aims to show the missing links and tell a complete story without shortcuts. It also differs from standard online repositories, where knowledge is heavily compartmentalised; instead, I try to view technical problems holistically to highlight how different fields connect to produce a solution. The notes reflect my personal outlook and how I understand these problems. Beyond tidying up my handwritten notes and archiving my learning digitally, I built this page to promote understanding of the fundamentals and their role in solving real-life scientific and engineering problems.
